MEDICAL DEVICE AND TECHNIQUE FOR USING THE SAME

摘要

According to various embodiments, a tracheal tube (12) may employ optical sensing techniques for determining a distance (d) between the inserted tube and an anatomical structure, such as a carina (28). The distance information may provide an indication as to whether or not the tracheal tube is properly placed within the trachea. The optical techniques may include backscattered intensity measurements.
